Waste metal treatment method using calcium and magnesium |
| abstract |
The present invention is a method for treating heavy metal-containing wastewater using calcium and magnesium inexpensive materials such as liver water (also known as high juice), which is a byproduct of decontamination process, and gypsum acid wastewater neutralization material, which is a decontamination process waste, and water glass (sodium silicate).n n n Injecting heavy metal-containing industrial wastewater containing calcium and magnesium into the wastewater according to the characteristics of the wastewater, injecting Ca ion concentration of 0.005-0.1 mol and Mg ion concentration of 0.005-0.1 mol in the wastewater; Is adjusted to 7-11, and auxiliary pH of the solution is adjusted with an alkaline agent such as caustic soda (sodium hydroxide), and after the solution is stirred for a few minutes, the stirring is stopped to cause aggregation to precipitate but generally precipitate and The dehydration rate is fast, but the polymer material may be used as a coagulant precipitation aid to increase the precipitation and dehydration rate. |
